We would like to take the opportunity to say here a few words about the Duo-Art recordings process (based on The Pianola Institute great informations)At New York AEolian Hall there was also a piano roll recording studio. "Unlike many other reproducing piano systems, the Duo-Art used a real-time perforator to produce an original roll as the artist played (...) Once a Duo-Art original had been perforated, it was copied to a much longer stencil roll, on thicker paper, which was then used to produce several copies for editing purposes, known as trials.""Whereas Welte in Germany did not invite pianists to assist with the editing of their own rolls, Aeolian made a feature of asking its well-known recording artists to help polish their performances. Percy Grainger observed that the Duo-Art represented him not as he actually played, but as he would like to have played."Please note that our Duo-Art for sale comes with 500 of these amazing music rolls !*From the Duo-Art piano roll catalog, page 23, we find under n°6475 that Edward GRIEG. Piano Concerto op.16, 1st movement has been performed by Percy Grainger, and it is what you will hear now, played on the Ghysels piano, by clicking on the video below.
